摘 要：
采用室内盆栽法,对不同蚯蚓粪(饵料为牛粪)添加量(体积比):0%、10%、20%和30%下大棚连作土壤中番茄幼苗生长及根际可培养微生物数量的变化进行了研究。结果表明:添加蚯蚓粪后可显著提高番茄幼苗的叶片增长率、株高,其值由高至低为30%>10%,20%>0%,差异显著。蚯蚓粪显著提高番茄地上部干重和根系鲜重;降低了根际真菌数量,减少了根际病害发生率;与对照相比,蚯蚓粪处理的土壤速效氮、速效磷、速效钾分别提高了24.4%~56.0%、24.3%~55.9%和40.0%~57.1%。但是,20%和30%添加量的土壤微生物和养分差异不显著,考虑植株生物量等其它因素,确定20%添加量更适宜连作番茄土壤的改良。总之,蚯蚓粪通过调节植物根际微生物环境和土壤养分等因子的变化减轻设施番茄土壤连作问题。

摘 要：
Effects of manure vermicompost application rates(volume ratio):0%(CK),10%,20% and 30% were designed in the experiment on tomato growth and microbes in rhizosphere in greenhouse soil of continuous cropping under pot experiments were studied.The results showed that the increments of leaves and plant height were stimulated by vermicompost,the sequence of leaves increment rate and plant height were both in 30%>10%,20%>0%(CK),and the difference was significant(P<0.05).Also the shoot dry weight and root fresh weight of tomato seedling grown in soil with vermicompost were more than that of control.At the same time,vermicompost inhibited fungi thrive in rhizosphere of tomato seedling.Comparing to control treatment,vermicompost accelerated available nutrients release in soil,the contents of available N,P,and K were more by 24.4%~56.0%,24.3%~55.9%,and 40.0%~57.1%,respectively.The difference between the 20% and 30% level of vermicompost was no significant in microbial populations and nutrients,it was believed that 20% addition into continuous soil was an appropriated rate.It was concluded that cow manure vermicompost eliminated continuous cropping soil problems by improving plant growth,microbial community,and by releasing more nutrients.It can be a good improvement agent for continuous soil and 20%(volume ratio) level was an appropriate rate.
